Serial Transmit block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Embedded Coder Support Package for Infineon AURIX TC4x Microcontrollers / AURIX TC4x

Description

Add-On Required: This feature requires the Embedded Coder Support Package for Infineon AURIX TC4x Microcontrollers add-on.

The Serial Transmit block writes data to the Universal Asynchronous Receiver Transmitter (UART) port on an Infineon^® AURIX™ TC4x Microcontroller board.

The block accepts a vector array of type int8, uint8, int16, uint16, int32, uint32, single, or double values.

To configure serial block peripherals, see Serial Peripheral Configuration.

Ports

Input

data — Data to transmit the UART port

vector

The port accepts the values to transmit to the UART port on the hardware board.

Data Types: uint8 | int8 | uint16 | int16 | uint32 | int32 | single | double

Output

status — Status of data transmission

scalar

The port outputs the data transmission status indicator as either 0 or 1.

• 0 — Successful write operation.

• 1 — Error in serial data transmission

Dependencies

To enable this port, set the Transfer mode parameter to Wait until previous data transmitted and select the Enable status port parameter.

Data Types: uint8

Parameters

Transfer mode — Mode of data transmission

Transmit data without waiting (default) | Wait until previous data transmitted

Select one of these operation modes:

• Transmit data without waiting — Transmit data to the peripheral device without waiting.

• Wait until previous data transmitted — The block waits until the previous data is completely transmitted before it continues transmitting the next data frame. This mode enables the Timeout(ms) parameter, which specifies the waiting time.

Timeout (ms) — Waiting time to complete write operation

0 (default) | scalar

Specify the maximum time to wait before transmitting the next data frame.

Dependencies

To enable this parameter, set Transfer mode to Wait until previous data transmitted.

Enable status — Option to output transmission status

off (default) | on

Select this parameter to enable the Status port, which outputs the transmission status.

Dependencies

To enable this port, set the Transfer mode parameter to Wait until previous data transmitted.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"aurixtc4xxlib/Serial Transmit"

Example: add_block("aurixtc4xxlib/Serial Transmit","myModel/myBlock",MakeNameUnique="on")
